So you're telling me that all of the surfaces inside a 'mech cockpit, where the temperature gets so oppressive that wearing a breathable heavy fabric like denim would make you pass out, are not made of metal? Every single surface is covered with something which is impervious to heat, thus rendering it safe to touch with bare skin?
IF SO, why didn't they just make pilot suits out of this miracle material?
IF NOT, then I reiterate: I'd rather wear full-body covering and be somewhat uncomfortable than risk first- and second-degree burns from the overheated metal in the cockpit. You're far less likely to pass out from 'heat exhaustion' (especially if you take precautions, like, oh, having a water-bottle with you) than you are to cause yourself multiple severe burns.
The 'shorts and cooling vest' camp is a result of poorly thought-out background material, and doesn't match the reality of thermodynamics.
Your argument does not make sense. It is entirely possible all surfaces inside the cockpit are covered in a rubber material. No, it does not make sense to wear a suit of rubber instead. Your body employs evaporative cooling, and the last time I wore a full-body rubber suit, sweat did not evaporate off my skin well at all.
I find it unlikely that you did not consider this, given the well thought out nature of your post. I can only speculate therefore that you are attempting to field erroneous arguments to further your "full suits are cooler" argument.
Stop. You're thinking "I can just reply with 'but what if the suit itself was cooled...' and he will be confounded!" No. You know as well as I do that it does not matter if the extremeties are allowed the same degree of conduction cooling as a vest, and that the limbs are best served to be open to air for evaporative cooling when compared to being covered in rubber. What you could say is that it would be better to be covered in some sort of material that would help negate the heat index effects of a very hot cockpit, but this would not stop discomfort from touching hot metal.

Then again, 'Mechs are not even meant to be operative in extremely high temperatures and they'll just shut down if the reactor is pushed to capacity - so, theoretically, the pilot in shorts wouldn't get burned; not most of the time.
Mechs only gain 1 heat if above 50 degrees
Celsius, and only at a rate of 1 heat per 10 degrees over. I'll do the math for you: 123f to gain 1 heat point. Assuming a 'Mech with single heat sinks and only equipped with the base 10 heat sinks, you need to reach 266f
and run to max your heat load.
So if we go up another 10 degrees, THEN you will start overheating, and with running every turn, it'll take over 2 minutes to even have a remote chance of overheating. If we look at the temperature required to absolutely shut down, you're looking at 8.3 minutes until shutdown.
Keep in mind that in both hypothetical situations, the outcome can be easily reversed by walking instead of running.
